Can't edit excel files in browser (SharePoint 2010)
One issue we are still having is that when traffic is going through the F5, after you open an excel file successfully in the browser, and then attempt to edit in browser by clicking the edit in browser button it generates "An error occurred, please try again." This also triggers a warning on the corresponding web front-end application event log from source "Excel Services Application" event id 2026, task category "Excel Calculation Services" the error is simply "An internal error occurred".
If you bypass the F5, the excel will open in the edit mode with generating any errors in the browser or windows event log.
We are using the F5 for SSL offloading as well.
Anyone seen this before or have any ideas for troubleshooting?
